FaithSteer-BENCH: LLM Steering Stress-Test Benchmark
FaithSteer-BENCH introduces a deployment-aligned benchmark for stress-testing inference-time steering in LLMs, evaluating controllability, utility preservation, and robustness at fixed operating points. It reveals failure modes like illusory controllability, cognitive tax on unrelated tasks, and brittleness to perturbations in existing methods. Mechanism diagnostics show many approaches induce prompt-conditional alignment rather than stable latent shifts.
Diff Eqs as DNN Theory Foundation
This arXiv survey positions differential equations as a principled foundation for understanding and improving deep neural networks. It explores three key questions on architectures, performance tools, and applications via model-level (whole DNN as ODE) and layer-level perspectives. The paper connects theory to design, analysis, real-world uses, and future challenges.
Corpus-Scale Unsupervised Transition Concept Discovery
A 29.4M-parameter contrastive model trained on 373M co-occurrence pairs from Project Gutenberg discovers transition-structure concepts, clustering texts by function like 'direct confrontation' rather than topics. It extends PAM for scalable concept formation, producing multi-resolution maps that transfer to unseen novels without retraining. Embedding similarity clusters by topic, while this groups by register and literary patterns.
Compression Order: Prune First or Quantize?
This arXiv paper investigates whether the order of pruning and quantization matters in joint model compression. It introduces the Progressive Intensity Hypothesis, stating weaker perturbations should precede stronger ones, supported by theoretical guarantees. Extensive experiments on language and vision models confirm its generality to multi-stage and mixed-precision setups.
Clinicians Shift AI Notes to Clinical Language
Ambient AI generates draft clinical notes using consumer phrasing, which clinicians edit to standardized terminology. Analysis of 71,173 note pairs shows significant reductions in terminology density, with 59.3% of transformations in Assessment and Plan sections. Findings reveal consistent clinician edits supporting section-aware AI design.
Iran War Inflicts Years-Long LNG Damage
Iranian missile strikes damaged Qatar's LNG facilities, with repairs taking 3-5 years and 17% export loss. LNG lacks strategic reserves, spiking European prices 35%. JPMorgan raises supply gap forecasts amid prolonged conflict.
Cursor Composer 2 Exposed as Kimi K2.5 Base
Cursor launched Composer 2 as enhanced AI coding model via pretraining and RL, but API revealed Kimi K2.5 base, sparking open-source license violation claims. Moonshot AI clarified authorized use via Fireworks AI platform. Not first controversy for Cursor's model origins.
OpenAI's North Star: AI Researcher by 2028
OpenAI reveals 'North Star' project for a fully autonomous multi-agent AI research system before 2028, with phase 1 'AI research intern' landing in Sep 2026. Integrates reasoning, agents, interpretability for self-running AI researchers. Anthropic counters with Claude Code Channels embedded in dev workflows.
Who Manufactures Batch AI Geniuses?
Highlights batch emergence of AI prodigies like Yao Shunyu, Yang Zhilin, Lin Junyang, Luo Fuli. Probes reasons behind the sudden surge of these talents.
Youth Go Viral on 'Prefrontal Cortex Damage'
Chinese youth are self-diagnosing prefrontal cortex 'damage' for procrastination and poor focus, sparked by computational neuroscience PhD Yang Yukun's relatable videos. The phenomenon blends memes, protection tips like better sleep, and self-mockery. Critics warn it trivializes genuine brain injuries from trauma or disease.
Yuejiang: Gala's Hidden Embodied AI with 10B Cap
Yuejiang CEO Liu Peichao discusses the company's subtle appearance in CCTV Spring Festival Gala as an embodied AI player. Despite this, Yuejiang has achieved a 10 billion RMB market cap. Embodied revenue has reached tens of millions RMB, moving beyond chasing fame.
